A study of common dimensions on the impression of color, fragrance and music

抄録

　In the present study, it aimed to extract common impression dimensions in 3 senses (color, music, and scent) with use of sensory information and examine a relation for each individual sense in the impression dimension. Color stimuli were selected on the basis of PCCS and total 25 stimuli (12 tones, 12 hues, and achromatic color) were used. The study used 30 kinds of scent stimulation mainly as food flavor. It also used music stimulation in 40 music categories selected from the preceding studies. These stimulations had impression evaluation with Semantic differential method (SD method) with 20 pairs of adjectives. In addition, color stimulation was evaluated for brightness and vividness with use of VAS. 37 people participated in the experiment. The study obtained 4 factors after extracting impression dimension by factor analysis. Integrated dimension for brightness and vividness was calculated for color tone stimulation by principal component analysis. The integrated dimension for this result was named as “Brilliantness”. When calculating correlation coefficient between the factor of “Brilliantness” and impression dimension, the study found a high correlation with Factor 1 and 2 in impression dimension; therefore, we decided to focus on these 2 factors. The study categorized each scent stimulation and music stimulation by cluster analysis. As the result, there were 8 groups/11 groups for scent/music stimulation respectively. When focusing on a relation for each color, scent, and music in Factor 1 and 2, the study recognized a distribution to the first/third quadrant for color/scent respectively while music indicated a distribution to the second/forth quadrant in addition to it.
